This issue has been a Pain in my !%#@$@ for the last 4 years and ruined many
Lower ends at Cal Speedway and
watching my OP drop to 20 lbs coming out of 13 at Buttonwillow drove me
crazy knowing that can't be good- Accusumps did not solve the issue, just
delayed the inevitable- Joe from Chequered Flag racing has a pan he now
produces which works perfect with a stock pick up- No trap doors for another
failure-- check it out here

Good luck!

Subject: [Fot] Spitfire oil pan baffling
> We're planning to improve the baffling in our Spitfire oil pans for next
> year and are looking for any input you might have. (I say "pans",
> plural, because we hope to have more than one Spitfire next year.) Any
> thoughts on how baffling should be done?

> The oil pan we're using is currently baffled as described in the
> original Comp Prep Manuals. There's a divider down the center of the
> pan (longitudinally) which goes from the bottom of the pan (with a small
> space underneath - approx. 1/4") and extending up to the level of the
> shallow part of the pan. In the divider is a big swinging trap door
> allowing oil to surge from the right side of the pan over to the left
> (where the pickup is), but not the other way. There are some approx.
> 3/8th" holes (6 or 8) drilled in the trap door.

> For the last couple of years, we've had no luck keeping Spitfire motors

> (OK, call me a slow learner) What we found out watching the big red

> baffling and see what happens next year.
